JUMP-4017 Brother is my onapetto ♯3. Aya-chan

Aya-chan, a cute girl who looks like a certain idol, has been staying at home for a long time, and I’m peeping at where Aya-chan is masturbating in the bathroom and where she’s having sex with her boyfriend. I have an older brother who is not a ronin. One day, he was found sneaking into Aya-chan’s room, and after that, his younger sister forced him to do cunnilingus like a daily routine, and he seems to be spending ecstatic days. An older brother who erects in his sister’s nakedness and a younger sister who doesn’t have low-class ideas… This older brother has this younger sister!
